This is definitely a must play, collect the bundle of money and the roof, and that's when the game really kicks off.
I didn't walk under the security camera's in the first half, but did on the second and seemed like I couldn't be detected?
Would love to see those vent covers come off and see a different part of a level entirely in the second half too, but I loved that you played with size on each floor on the second way through!
Also as a Godot dev, I would love to know how you do your low poly or share a resource, because this is so cool.
(P.S. your links to the poly.pizza lead to 404 errors)
